Art of Koiwriting – a tutorial for the constructed language, Tsevhu

I have no association with this. Just stumbled upon the video and thought to share.

It seems they created their own language (a conlang) which is cool enough in itself. But what puts this one apart is that they have this ceremonial writing system which looks like koi fishes in a pond. The "letters" are concentric rings on a ripple. The shape and decoration of the ripple describes which letter it is.

The grammar of the sentence is expressed where the ripples appear in relation to the fish's body.
